To all whom it may concern: Q designates the outlet-pipe, leading from Be it known that I, JOHN SMITH, a citizen the cap (3, which may be one continuous pipe of the United States, residing in the city and or formed in sections, as indicated in Fig. 1, county of Philadelphia, State of Penns'ylvasaid outlet leading into the chamber or res- 5 nia, have invented anew and useful Improveervoir R, which is provided near its upper porment in the Manufacture of Candy, which imtion with a partition or diaphragm S, which provement is fully set forth in the following has the perforations T therein. specification and accompanying drawings.

After the sugar and glucose have been treated to the desired extent, it be ing of course understood that the valve F has remained closed while the above operation has taken place, the said valve can be opened, as seen in Fig. at, and the sugar and glucose which have been sufficiently treated are allowed to fall upon a table or bed, upon which they can be worked to the desired degree.

Especial attention is called to the fact that by having the kettle subdivided in the manner described, and by employing separate heating means in the several compartments, I am enabled to subject the material in each compartment to different intensities of heat, and when the operation is completed the contents can be quickly and expeditiously removedfrom the kettle and the compartments thereof readily refilled. It will also be noted that by applying a uniform degree of heat to the exterior of the body B and variable de grees of temperature to the interior compart ments very effective results are attained.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A \"acuun1 l-;ettle, an upright partition supported within said kettle forming compartments, means within each compartment for independently heating the same, a single exit-pipe receiving from both compartment-s simultaneously and having a valve thereon.

2. A duplex vacuum-kettle, consisting of a body, a cap therefor, a jacket around said body, a partition in the latter, a heating-pipe located in each compartment on either side of said partition, means for conducting a heating fluid to and from each of said pipes, an outlet-pipe leading from said cap, a chamber in communication with said outlet, a perforated diaphragm in said chamber, means for introducing a cooling medium above said diaphragm, and means for withdrawing the products of condensation from said chamber.

8. A duplex vacuum-kettle, consisting of a body, a cap therefor, a partition located within the same, a heating-jacket surrounding said body, means for independently heating each side of said partition, independent outlet-ports communicating with the lower portion of said body, and a valve for controlling said ports.

4. A duplex vacuum-kettle, an upright partition, located within the same, a heatingjacket surrounding said kettle, means for independently heating each side of said partition, independent outlet-ports communicating with the lower portion of said kettle, and a valve for controlling said ports.

5. A duplex vacuum-kettle, having a jacket surrounding the lower portion, a partition in the latter forming compartments, means for independen tlyheatin g said compartments, an outlet from the upper portion of said kettle, a chamber into which said outlet discharges, an apertured diaphragm in the upper portion of said chamber, means for cooling and condensing the gaseous products evolved, means for withdrawing the same from said chamber, an outlet-passage leading. from said body at either side of said partition, and a valve controlling each passage, whereby the contents of both compartments of the kettle can be simultaneously withdrawn.
